Control44
4 bit Address - 4 bit Data encoder/decoder
Control44 is a 4 bit address, 4 bit data
encoder and decoder combined in a single
IC. This device can operate in either Encode
or Decode mode. It uses 1kbps differential
Manchester bit balancing with preamble
and
checksum.CTR44
is
specifically
designed to be used in RF remote control
applications. It is available in 20pin SSOP,
18pin SOIC and PDIP packages.

Features
Operating voltage (temperature):
3.0V-5.5V for standard version (-40°C to +125°C)
2.0V-5.5V for low voltage version (-40°C to +85°C)
Draws <2mA without external load
4 bit address and 4 bit data
16 different remotes with 4 controls each
Single packetised transmission for fast activation
Maximum usage of the range capability of an RF module
Adequate preamble to settle data slicer in the receiver.
Extra wake up preamble to allow for transmitter power up time requirements
Differential Manchester encoding of address, data and checksum
Synchronisation codes and checksum to reduce false triggering on noise
